[QUOTE="RegionRat, post: 1449871, member: 57231"] What you are looking for is lots of copper fouling in the first parts of the throat and lands. Then anywhere else downstream in the bbl. Rough spots where the lead angle is cut into the lands will cause that ogive seating depth number to change quickly and also to foul. Any downstream rough spots that are tearing up the bullet jacket are also a contributor to excess copper fouling. [/QUOTE]
